Can the Assistant execute a function call internally?

I’m sure if this is the right approach for the task. Here’s the situation:

I’m building a chatbot powered by the beta Assistant API. To put it simply, the conversation has different “stages”.

Depending on the stage of the conversation, I inject additional instructions into the system prompt in the Run object using the additional_instructions parameter.

However I need to find a way to transition between stages, and one of the ways I thought about achieving so, was to use function calling so every time the User sends a message, the Assistant analyzes past messages and the most recent User message to determine if it has all the context needed for the current stage, AND change the “stage”.

But it doesn’t work and it doesn’t feel natural…

Should I create a separate module that is only dedicated to analyzing the user messages to determine if it should move the stage of the conversation?

Here’s a thought that might help. Consder that a RUN acts on a THREAD. And a run akways ends after some processing that (including function calling) that is based its prompt. At that point, you can add more message to the thread and CREATE A NEW RUN (you have to!). But what I didn’t realize in the beginning is that nothing is keeping you from doing that run with a complately different (more appropriate) assistant. You can even end every run with a recommendation about what it thinks should be the next run (or phase). For too long in mind thread and run where ‘coupled’ - but they really arent.
Hope that helps

Instead of incrypticing each section, and decription, write the code as a whole and then have it separate it functions into your desired parts?

Thanks for your response — Just to make sure I understood correctly: You suggest passing the current conversation (thread and messages) to a different Assistant 2 from the Runs of Assistant 1?

The Assistant 2 job would be to analyze the current conversation, and determine if it’s time to move on with the conversation for Assistant 1.

It seems feasible — Didn’t think about leveraging the Run capabilities to build a multi-agent workflow.

So literally when you have run ‘complete’ (which in case a of non streaming assistant with no function calling is every time you receive an answer back) you add a new message to the thread and then create a new run. The run has an assistant attached to it. The thread does not. So yes you ‘pass the thread around’ to different assistants. The only limit is that you can only have one active run per thread.

I read your explanation in the email notification I received when you posted. I’m not sure why you deleted it because it was a GREAT answer!

I’m not very confident I’m self taught. I’m very happy I helped :heart:

The approach you’ve outlined for transitioning between stages in a chatbot conversation using the Assistant API is a common challenge, especially when trying to make interactions feel natural and flow logically. Using function calling to handle stage transitions might feel a bit awkward and unnatural because it’s more suited for task-based actions like retrieving specific information or performing an operation.

Here’s a more structured approach to handling conversation stages that could make things feel more natural:

1. Use a Conversation State Management Layer

Instead of having the assistant handle stage transitions purely via function calls, you can implement a state management layeroutside of the Assistant API that tracks the current stage of the conversation and determines when a transition should occur. This state management module would:

  • Keep track of what stage the conversation is in.
  • Analyze user inputs to see if the necessary information has been provided for the current stage.
  • Transition to the next stage when appropriate.

This external module acts like a conversation “orchestrator,” and ensures that the Assistant API receives the correct context at every step.

Key Steps:

  1. Track Conversation Stages: Create a state machine that represents the different stages of the conversation (e.g., Introduction, Product Details, Purchase Confirmation).
  2. Define Transition Criteria: For each stage, define what criteria must be met to move to the next stage. These could be based on the user’s input, the assistant’s response, or a combination of both.
  3. Handle Transitions: Once the criteria are met, your state manager updates the stage and adjusts the instructions passed to the assistant accordingly.

2. Use Function Calls for Data Processing, Not Stage Management

Function calling in OpenAI’s models is more naturally suited for processing data (e.g., pulling information from a database, performing calculations, etc.) rather than managing conversation stages. You can still use function calls within each stage to handle specific tasks (like fetching product details or placing an order), but don’t rely on them for conversation flow.

Here’s how you could structure it:

  • Stage 1: Introduction — Gather user information.
    • If function call: fetch user preferences.
  • Stage 2: Product Information — Provide product details.
    • If function call: retrieve product specs.
  • Stage 3: Checkout — Assist with purchase.

Once the necessary data is collected or the conversation flow reaches a natural end, your external module updates the stage.

3. Dynamic Instructions in the System Prompt

Use the additional_instructions in the Runobject dynamically based on the current stage. These additional instructions can change based on what stage the conversation is in. For example:

  • Introduction Stage: “You are helping the user get acquainted with the service.”
  • Product Information Stage: “You are assisting the user in choosing a product.”
  • Checkout Stage: “You are helping the user complete a purchase.”

In this model, the assistant doesn’t control stage transitions directly, but instead, the state manager updates the system instructions based on the user’s progress through the conversation.

4. Predefined Stage Transitions Based on Milestones

Instead of relying on function calls for transitions, use milestones based on user inputs to trigger transitions. For example:

  • Once the user provides enough information during the “Introduction” stage, the assistant will automatically move to the “Product Information” stage without the need for function calls.
  • When the assistant detects a key milestone (e.g., “I want to buy X”), it automatically transitions to the “Checkout” stage.

This allows for a more natural and fluid conversation flow.

Example of Handling Stages

1. State Management Layer (External Module)

let conversationState = {
    stage: "Introduction",  // Possible values: "Introduction", "ProductInfo", "Checkout"
};

function updateStage(userMessage) {
    if (conversationState.stage === "Introduction" && userMessage.includes("product details")) {
        conversationState.stage = "ProductInfo";
    } else if (conversationState.stage === "ProductInfo" && userMessage.includes("buy")) {
        conversationState.stage = "Checkout";
    }
}

2. Modifying Instructions Based on Stage

function getAdditionalInstructions() {
    if (conversationState.stage === "Introduction") {
        return "You are introducing the user to the service and collecting preferences.";
    } else if (conversationState.stage === "ProductInfo") {
        return "You are helping the user compare product details and make a decision.";
    } else if (conversationState.stage === "Checkout") {
        return "You are assisting the user with the checkout process.";
    }
}

// Update the Run object with the dynamic instructions
const run = await openai.beta.threads.runs.create(thread.id, {
    assistant_id: assistant.id,
    additional_instructions: getAdditionalInstructions(),
});

5. Monitor User Inputs Continuously

You can continuously analyze user inputs as they come in, checking whether certain milestones (key phrases or patterns) have been met. Once these are triggered, the state is updated and the conversation can naturally transition to the next stage.

For example:

  • Milestone for Product Stage: User asks for product details.
  • Milestone for Checkout Stage: User indicates readiness to buy.

6. Use Function Calling for Contextual Actions

While your state manager handles conversation stages, function calling can be used to take specific actions like fetching product data, applying discounts, etc. This way, function calls are triggered as part of the conversation but not for managing the conversation flow itself.

Final Thoughts

In summary:

  • Separate the stage management: Use an external module to manage conversation stages and transitions, leaving the assistant to handle the interaction itself.
  • Use function calls: Use function calling for task-specific actions (fetching data or performing backend actions) rather than managing the flow of conversation.
  • Dynamic instructions: Use the additional_instructions parameter to adjust the assistant’s behavior and context based on the current stage of the conversation.
  • Analyze user input: Build logic to monitor user messages and determine when a stage transition is needed.

This approach will make the conversation flow more naturally, avoid rigid or awkward transitions, and allow you to extend the assistants capabilities over time. Let me know if you need further clarification or help with implementing this! Sorry copy paste from the delete edit messed up formatting. This was my solution if it is helpful.
